There was a accident that left you as a small toon but you were just ditched but since you were the size of a bug. No toon or Twisted ever noticed you. However while walking around and avoiding to be squished by accident. You found a nice plush of Shelly to lay under however it was picked up by Gigi and she opened the top of her Gachapon head and dropped it in with you.

Gigi: "Nice plush. Gonna keep that to my collection. It was an easy score for me. My collection just gets bigger and bigger. Something did feel a bit off but who cares really. Well time to go back to my room."
